Application filed January 6, 1915. Serial No. 714.

To VZZ fwwm may Concern Be it, known that I, JOSEPH KNiTLE, a citi- Zen of the United States, residing at Minneapolis, in the county of Hennepin and State of lilinnesota, have invented certain new and useful Improvements in Levels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in levels; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a side elevation of the improved level with the end portions thereof broken away; Fig. '2 is a view partly in plan and partly in horizontal section taken on the line x2 002 of Fig. l, on an enlarged scale; Fig. 3 is a view partly in side elevation and partly in section taken on the line m3 w3 of Fig. 2; and Fig. 4 is a view principally in transverse section taken on the line x4 m4 of Fig. 3.

The numeral l indicates a rectangular wooden body member having at its intermediate portion, a rectangular recess or chamber 2. This chamber 2 is open at its top and one side, and, as shown, the lower portion thereof is contracted to afford a pair of shoulders 3, spaced longitudinally of the body l. The open top and side of the chamber 3 are normally closed bv transparent panels -LL and 5 respectively. 'Ihese panels a and 5 are mounted in ametallic skeleton frame 6, secured by screws to the body l. Obviously, by removing the frame 6, access may be had to the chamber 3.

Projecting vertically from each shoulder 3, is a screw stud 7, that is rigidly anchored to the body 1 and provided with a pair of opposing, adjusting nuts 8. Adjustably supported on the studs 7 between the coperating pairs of nuts 8, is a bed-plate 9. Formed inthe bed-plate 9, is an L-shaped slot l0,

the short leg of which extends completely through one of the longitudinally edges, of said bed-plate. A dial l1, graduated to indicate degrees, is extended vertically through the long leg of the slot 10 and is rigidly secured to the bed-plate 9. Extending axially and loosely through the dial 11.I is a relatively short shaft l2 having conical ends that are mounted in conical seats, formed, one in the main body of the bedplate 9, and the other in a screw plug 13. This screw plug 13 has screw threaded engagement with the prong of the bed-plate 9, extends transversely therethrough and is provided for the well known purpose of taking up wear. Rigidly secured to the shaft l2, is a gravity arighted indicator, as shown, in the form of a weighted pointer 14, arranged for cooperation with the dial l1.

To adjust the improved level, the body 1 may be placed in a true horizontal position, and then by adjusting the nuts 8 on one of the studs 7, the bed-plate 9 may be raised or lowered at one end, to bring the zero point on the dial 1l into registration with the pointer 14. The purpose of making the slot l0 L-shaped, is to permit the dial to be read when the level is turned into vertical position.

By means of the improved level, the body l may be set in either true horizontal or vertical positions or in different degrees of Obliquity with respect to the horizontal.

W'hat I claim is:

l. In a level, the combination with a body member having a recess, of` a bed-plate mounted in said recess and having an L- shaped slot extending through one edge thereof, a dial mounted in said slot on the bed-plate at the axis of the screw plug, and a gravity arighted indicatorjournaled at the axis of said dial for cooperation therewith.

2. In a level, the combination with a body member having a recess, of a bed-plate mounted in said recess and having an L-Y shaped slot extending through one edge thereof, an adjustable screw plug mounted in the prong of said bed-plate, a dial mounted in the long leg of said slot on the bedplate at the axis of the screw plug, and a In testimony whereof I ailix my signagravity al'ighted indicator, aihianged for cotui-e in presenceof two witnesses. operation with said dial and aving a shaft extending axially therethrough, said shaft JOSEPH KNILE j having conical ends mounted in conical Witnesses:

seats formed, one in the main body of said BERNICE G. VHEELER, bed-plate and the other in said screw plug. HARRY D. KILGORE.
